Filed: 2001-03-20
Abstract: PURPOSE: A method and device is provided to improve a machine tool such that with different, initially unknown materials to be cut, an optimal holding coefficient is always achieved in the substrate without risk of mishandling of the device resulting in an unavoidable worsening of the holding coefficients. CONSTITUTION: A method for hand-operated machine tools, particularly for hammer drills, for optimal cutting of different substrates by energy adaptation, is characterized in that the machine tool, when turned on, is operated initially-preferably in a pre-selectable manner-in a first operating state(I) with reduced power consumption at reduced nominal voltage, and after a predetermined time period, a second operating state(II) with increased power consumption at full nominal voltage of is switched to automatically. In the first operating state with reduced power consumption, the single-blow energy is reduced and/or the hammer rate and rotational speed are decreased. In particular, such a method ensures that cutting is carried out without damage in the case of hollow block material and a precise tap-drilling is ensured in the case of solid material. In the second operating state with increased power consumption, the single-blow energy and the frequency and rotational speed are adjusted to an increased desired value ensuring fast setting of a bore hole.
